JavaScript by Example
by Dani AkashJavaScript is the programming language that all web developers need to learn. Its flexible, simple, and powerful, but knowing where to start can be intimidating. Even if you've barely touched JavaScript before, the projects in this book will have you building amazing JavaScript applications in no time. This book takes you from beginner to winner with JavaScript. Through a series of engaging projects that showcase how easy it is for you to create great things with JavaScript, you will learn the essentials of modern JavaScript. The techniques and tools you use to build your projects are the cornerstone of professional JavaScript development, and you'll get a great grounding in all the things that count. The first item on our JavaScript to-do list is to build a To-do list app, which you'll have done by the end of the first chapter. You'll meet DOM manipulation with JavaScript and work with event listeners, which will give you a good idea on how JavaScript works with HTML elements of your pages. You'll work with images and text to build a Meme creator. While developing this app, you will learn about the Canvas element, used for drawing graphics. You will also learn about ES6 (ECMAScript) Classes, and be introduced to layouts using the CSS3 flexbox. You will then build a weather application, which will show you different methods of performing AJAX requests and working with dynamic, external data. You'll also develop a responsive Event Registration form with powerful form validation which allows users to register for your upcoming event and use charts and graphics to display registration data. WebRTC enables real-time communication in a web browser. You'll learn how to use that as well, when you build a real-time video-call and chat application later in the book. Towards the end of the book, you will meet React, Facebook's JavaScript library for building user interfaces. You'll simply throw together a blog with React, and get the sense of why this kind of JavaScript framework is used for building large scale applications. To make your blog more maintainable and scalable, you'll be using Redux to manage data across the React components.

JavaScript for Data Science (Chapman & Hall/CRC Data Science Series)
by Greg Wilson Maya Gans Toby HodgesJavaScript is the native language of the Internet. Originally created to make web pages more dynamic, it is now used for software projects of all kinds, including scientific visualization and data services. However, most data scientists have little or no experience with JavaScript, and most introductions to the language are written for people who want to build shopping carts rather than share maps of coral reefs. This book will introduce you to JavaScript's power and idiosyncrasies and guide you through the key features of the language and its tools and libraries. The book places equal focus on client- and server-side programming, and shows readers how to create interactive web content, build and test data services, and visualize data in the browser. Topics include: The core features of modern JavaScript Creating templated web pages Making those pages interactive using React Data visualization using Vega-Lite Using Data-Forge to wrangle tabular data Building a data service with Express Unit testing with Mocha All of the material is covered by the Creative Commons Attribution-Noncommercial 4.0 International license (CC-BY-NC-4.0) and is included in the book's companion website at http://js4ds.org . Maya Gans is a freelance data scientist and front-end developer by way of quantitative biology.

JavaScript with Promises: Managing Asynchronous Code
by Daniel ParkerAsynchronous JavaScript is everywhere, whether you’re using Ajax, AngularJS, Node.js, or WebRTC. This practical guide shows intermediate to advanced JavaScript developers how Promises can help you manage asynchronous code effectively—including the inevitable flood of callbacks as your codebase grows. You’ll learn the inner workings of Promises and ways to avoid difficulties and missteps when using them.The ability to asynchronously fetch data and load scripts in the browser broadens the capabilities of JavaScript applications. But if you don’t understand how the async part works, you’ll wind up with unpredictable code that’s difficult to maintain. This book is ideal whether you’re new to Promises or want to expand your knowledge of this technology.Understand how async JavaScript works by delving into callbacks, the event loop, and threadingLearn how Promises organize callbacks into discrete steps that are easier to read and maintainExamine scenarios you’ll encounter and techniques you can use when writing real-world applicationsUse features in the Bluebird library and jQuery to work with PromisesLearn how the Promise API handles asynchronous errorsExplore ECMAScript 6 language features that simplify Promise-related code

by Simon Timms Ved Antani Dan MantylaUnlock the powers of functional programming hidden within JavaScript to build smarter, cleaner, and more reliable web apps About This Book * Write powerful code with the high-level functions that JavaScript offers * Discover what functional programming is, why it's effective, and how it's used in JavaScript * Understand and optimize JavaScript's hidden potential as a true functional language Who This Book Is For If you are a JavaScript developer interested in learning functional programming, looking for the quantum leap toward mastering the JavaScript language, or just want to become a better programmer in general, then this book is ideal for you. This guide is aimed at programmers, involved in developing reactive frontend apps, server-side apps that wrangle with reliability and concurrency, and everything in between. What You Will Learn * Get a run through of the basic JavaScript language constructs * Code using the powerful object-oriented feature in JavaScript * Master DOM manipulation, cross-browser strategies, and ES6 * Understand the basic concurrency constructs in Javascript and best performance strategies * Harness the power of patterns for tasks ranging from application building to code testing * Build large-scale apps seamlessly with the help of reactive patterns * Explore advanced design patterns, including dependency injection * Develop more powerful applications with currying and function composition * Create more reliable code with closures and immutable data In Detail JavaScript is a high-level, dynamic, untyped, lightweight, and interpreted programming language and functional programming is a style that emphasizes and enables smarter code that minimizes complexity and increases modularity. It's a way of writing cleaner code through clever ways of mutating, combining, and using functions. And JavaScript provides an excellent medium for this approach. By learning how to expose JavaScript's true identity as a functional language, we can implement web apps that are more powerful, easier to maintain and more reliable. The java script: Functional Programming for JavaScript Developers course will take you on a journey to show how functional programming when combined with other techniques makes JavaScript programming more efficient. The first module Mastering JavaScript, stress on practical aspects of Javascript development like--Functions and Closures, Runtime debugging techniques, project layout, events and DOM processing, build tools, Object-oriented patterns, isomorphism--everything that a modern Javascript project would need. The second module, Mastering JavaScript Design Patterns - Second Edition, will explore how design patterns can help you improve and organize your JavaScript code. You'll get to grips with creational, structural, and behavioral patterns as you discover how to put them to work in different scenarios. This updated edition will also delve into reactive design patterns and microservices as they are a growing phenomenon in the world of web development. It will also show you some advanced patterns, including dependency injection and live post processing. The third module, Functional Programming in JavaScript, will help you to write real-world applications by utilizing a wide range of functional techniques and styles. It explores the core concepts of functional programming common to all functional languages, with examples of their use in JavaScript. Style and approach This course will begin with providing insights and practical tips on advanced JavaScript features to build highly scalable web and mobile system and move on to some design patterns with JavaScript. Finally, the course ends with presenting the functional programming techniques and styles in JavaScript.
